Primary objective is to study the safety and effectiveness of the Nellix System for Endovascular Abdominal Aortic Aneurysm (AAA) repair. Procedures will be performed per the instructions for use, and per institutional protocols and standard of care for endovascular aneurysm repair. As such, this study will evaluate the safety and effectiveness of the device system among a wide range of physicians and in consecutively enrolled subjects to assess outcomes generalizability.
